flhisinventionrelates to method and apparatus or applyingv a coating to the inside oli paint buckets.`

ln the marketing or' certain products, such, 'for instance, as White lead, the article is prepared lor the market by packing in containers. ln the case of White lead, these containers are ordinarily metal cans. ,Preparatory to depositing the material inthe con-` lu tainer, it is desirable to coat the interior of the container with a. fluid, such as linseed oil. ihis process may be carried out by spraying the interior or each` container With linseed oil. i

@ne ot the objects of this invention theretore is to provide a useful method and apparatus whereby the coating Vmay be applied to the inside ot a paint bucket in a simple and eilective manner. t

Further objects will appear :trom the detail description taken in connection with the ac companying drawing, in which:

Figure l is a plan view oi a device enr bodyinfg this invention; i

Figure 2 is a side elevation of the same and Figure d is an enlarged sectional view showing' the construction ofthe nozzle.

Referring` to the accompanying drawing, l designates a base having* legs or other, suitd able supports 2. Movably mounted on the base l is a table 3 carried by springs d resting on the base l and guided by lguide-rods 5. rlhis mounting renders the table resilient so that it maybe depressed by the operator.

Rigidly mounted on the base l is a support 6 to which is attached a conduit 7 connected `with a source oit fluid supply, not shown. Within the supporto is afchainber 8 in the outlet of which is slidably mounted a tubular member 9 abutting at its top against the underside of a cup or depression l0 formed in the table 3 at its center. The upper end ot the member 9 is internally threaded to re ceive a cap ll which serves to clamp theinember 9 to thetable 3 andvvhich is provided with a tapered bore l2 adapted to provide a nozzle. rlhe member 9 together with thef cap 1l provide a movable nozzle communi# eating; with the chamber 8. y The lower end el the spray 6 is providedvvvith a valve seat 1,3 adapted tor cooperationvvith a valve lll carried by a. shank 15 rigidly secured at 16 to t-hevlovver end o'l3 the tubular member 9. The valve 14 is thus attached to the nozzle so liVhenthe table 3 is: `depressed,,the member@ as to be movable therewith `and thereby.`

is moved downwardly inthe support Geo to carry the valvelltaway from its seat-so as to `admit the fluid to the chamber trom which it escapes through the nozzle l2. The table"3 may be provided With perforations 1T through which the fluid may be drained from the table. i y i y ln using this device, the conduit 7 having been connected to a source of fluid supply under suilicient pressure to causethe fluid to; issue from the nozzle 12, the operator simply takes the container 18 and placing it in in vcrted position on the tableB and over the nozzfc,-depresscs the saine so as todepress the table. This will operate the valve 141; so as to permit the fluid4 to issue from the nozzle and spray the interior: of the container 18. llhe container may thus` be completely coated on its inside with a lihnot the fluid and the excess tluiddrains ott through the perlforations l?. i lt 'will be seen, there-tore, that this invention provides a simple and effective method and apparatus for applyinga coating to the inside of paint buckets, and one which saves considerable time in the operation. The i more placing. of the container uponthe table and depressing the saine tor a moment is suite cient to coat the interior of the container. fifi -The proiection of the stream of coating maferial under pressure and upwardly against the bottom of the bucket, not only `coats the bottom but also causes the fluid to lovv along and also coat the side Walls thereof,` the sur-` plus draining on and through the table.` y

lt is obvious that various changes may be made in details of construction 'Without de pasting from the spirit of this invention; it is, therefore, to be understood that this invention is not to be `limited to the specific detailsshoivn and described.` i i p Having thus described the invention, what. isclaimed is: f y i l. An apparatus for coating; the interiors of metal paint buckets Withoil, comprising, a supportl spring members mounted on thetop ther-ect', a table `surl'ace mounted. on said Aspringsadapted to position an inverted bucket, and depressible thcreaneinst by said buclet, a nozzle connected to receiveoil from a source oit oil supplied under pressure, and attached to said table surface at a depressed portion thereof, for movement therewith and arranged to direct the oil against the bottom of the inverted bucket so as to iow along' the side walls thereof, and drain on said table surface; openinvs through said surface to permit drainage therethrough, and a valve rigidly connected to said nozzle and to said table for o eration by movement of said nozzle and tab e. p

2. An apparatus forcoating the `interior of metal paint buckets with oil, comprising a support having a connection to a source of oil under pressure rigidly mounted therein, said d connection having a nozzle slidably mounted therein, said nozzle having a valve rigidly attached thereto and adapted to seat against said connection; a table having a depressed portionthereof rigidly secured to said nozzle for movement therewith, spring membersA mounted on said support around said connection and beneath said table to maintain said table, nozzle and valve normally inoperative, said table being depressible` to operate the valve and adapted for engagementby a bucket inverted thereon and over said noz zle, whereby depression of the bucket will depress the table to operate the valve, said table having drain openings therethrough around said depressed portion. In testimony whereof I affix this 22nd day of January, 1924.
